Draught Stabilisers

Draught stabilisers are designed to create exactly the right conditions for combustion. High up-draughts, experienced in windy or tall chimney locations, can adversely affect performance. Where this is likely to occur, we recommend a draught stabiliser to maintain the draught at the appropriate level. They can be used with gas, oil and solid fuel appliances.

The Haas+Sohn energy saving draught regulator constantly evens out the changes in the draught in the chimney that may be caused by external weather conditions (cold, wind). If the draught in the chimney becomes too strong, the shuttle valve opens and air flows into the chimney from the heating chamber. The low pressure (fireplace draught) at the boiler therefore remains constant, permitting optimum combustion. The shuttle valve will open even when the system is not operational, ventilating the chimney and thereby allowing the boiler to retain heat. Constant ventilation also reduces sooting up within the chimney.
With the Haas+Sohn energy saving draught regulator with an explosion damper. The explosion damper opens in the event of minor explosions that might occasionally occur in the boiler. In this way the short term excess pressure is easily released and damage to the heating unit is effectively prevented. To find out more information please download the Haas and Sohn Brochure.

Aircore Ventilators

Rytons Aircore Ventilators are a cowled appliance and room ventilator. The outer cowl and internal baffles reduce light and draughts and are U.V. stabilised. These can be used on new and refurbishment projects and are the only ventilators recommended by HETAS to their registered engineers.

Exodraft Chimney Fans

Exodraft chimney fans are designed to provide an accurate and fully controllable updraught for your chimney. They eliminate problems caused by downdraught, badly proportioned chimneys and negative pressure in the room due to extractor fans. The fans operate, preventing spillage into the room and enable installations of larger fireplaces which are connected to a chimney with a small flue diameter.
